Still not 100% sure but I'm working on it....

As soon as I know I WILL name & shame,it's up to admin if they ban the person or not as it was myself which brought into the open,but I think other forum members have a right to know there is a possible troll or trouble maker on the forum.
Sooner or later whoever it is will slip up,they have already made a couple of mistakes,by using my forum name in the email,an email address which has been traced and an IP which links to the email and to which part of the UK this person lives.

I'm working on a few other bits and pieces,it seems this person is full of wind and idle threats
